Data representing the same interactive grahic design vary greatly from one graphics system manufacturer to another. Therefore, translating the data into a common form to effect data base exchange is a difficult problem. This study examines the use of the Gerber language as a common data form through which design data could be exchanged between unlike systems. For this study Applicon Graphic System was used cyclically to check retention or degeneration of the data integrity when the original design was extracted/defined in the Gerber language and reentered into the AGS utilizing various Gerber Interface Programs. The various parts of this study include the transferring of data not only in the 2D environment, but 2D to 3D and 3D to 2D. Even though plots of the files appear very similar, the individual data bases are very dissimilar. Programs, both present and future, that might supply needed information or design aids and characteristics would find it virtually impossible to do so from a data base lacking the sophistication and completeness of the original AGS data base. Man-machine hours required to bring the data base back to original quality would be extensive. The loss of data base integrity shown by this study was restricted to an AGS to AGS transfer. The loss could very easily be magnified if the transfer were between unlike systems. 8 figures. (RWR)
